关于正常人骨密度测定已有很多的报道，但对常用取材的四个体位的相关性分性分析报道不多，且用DXA法对正常人进行骨密度测定的报道也很少，为此我们做了50例的检测分析．现报道如下：1材料与方法1．1测量对象：本组50例正常人中，男26例，平均年龄21．1（18～24）岁，女24例，
There are many reports on the measurement of bone mineral density in normal people, but there are few reports on the correlation analysis of the four body positions of commonly used materials. There are few reports about the bone mineral density measurement by DXA method in normal people. Therefore, we do 50 cases of detection analysis. Are reported as follows: 1 Materials and Methods 1.1 Measuring objects: The group of 50 normal people, 26 males, mean age 21.1 (18-24) years old, 24 females,
